drm/sun4i: Add alpha property for sun8i and sun50i VI layer
DE3.0 VI layers supports plane-global alpha channel. DE2.0 FCC block have GLOBAL_ALPHA register that can be used as alpha source for blender. Add alpha property to the DRM plane and connect it to the corresponding registers in the mixer. Do not add alpha property for V3s SOC that have DE2.0 and 2 VI planes.
